Spring测试camel事务没有附加

Question

我正在努力获得一些我写的回滚交易的测试。我的测试通过并且正常工作。但是，当我尝试使其成为事务性（因此我可以回滚测试）时，我收到以下错误

java.lang.IllegalStateException: Cannot start a new transaction without ending the existing transaction.
    at org.springframework.test.context.transaction.TransactionalTestExecutionListener.beforeTestMethod(TransactionalTestExecutionListener.java:175)        ~[spring-test-4.1.6.RELEASE.jar:4.1.6.RELEASE]
    at org.springframework.test.context.TestContextManager.beforeTestMethod(TestContextManager.java:249) [spring-test-4.1.6.RELEASE.jar:4.1.6.RELEASE]
    at 

如果我在路由中抛出异常，它将撤消任何数据库保存，因此我所拥有的事务确实有效......它似乎不会将自己附加到测试和回滚中？

我的测试看起来像这样。

@RunWith(CamelSpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {TestAppConfig.class})
@Transactional
public class RouteTest
{

    @Autowired SignUpRoute signUpRoute;

    @Test
    public void basicTest() throws Exception{

        ModelCamelContext signUpRouteContext = signUpRoute.getContext();

        MessageDto messageDto = new MessageDto();
        messageDto.setFirstName();
        messageDto.setLastName();
        // etc

        ObjectMapper mapper = new ObjectMapper();
        String jsonMessage = mapper.writeValueAsString(messageDto);  

       String rabbitURL = "rabbitmq://docker:5672/ignUp.exchange?queue=...etc...";

        ProducerTemplate producerTemplate = supplierSignUpRouteContext.createProducerTemplate();
        producerTemplate.setDefaultEndpoint(END_POINT_MOCK);
        producerTemplate.sendBody(rabbitmqURL, jsonMessage);

        END_POINT_MOCK.expectedMessageCount(1);
        END_POINT_MOCK.assertIsSatisfied();
    }   
}
